Telethia, the Endbringer (Japanese: 終焉のテレシア, Shūen no Tereshia) is a Tyrant in Xenoblade Chronicles X. It is a form of the Telethia and is found in Noctilum, above the Divine Roost. At level 99, it is the most powerful enemy in the game, yet it is non-aggressive and will not attack the party first.
The battle with Telethia, the Endbringer begins in the air, but Telethia, the Endbringer will descend onto the ground when it has less than 60% of its HP. It will later return to the sky if the battle lasts long enough. If it is in the middle of descending or ascending, it is immune to all attacks.
It must be defeated during one route of A Fateful Choice. Defeating it as part of the mission will not count towards segment recon.

"This giant indigen circles the skies of Noctilum, making its home in the giant trees there. It's rather unpredictable, and has even been known to assist BLADEs."
